With water conservation demands growing very year, accurate and reliable flow measurements have become critical to water management decisions. Now you can enjoy the benefits of high-precision flow managements in less time than ever, while keeping it affordable. Whether looking to measure flow in rivers, streams or canals, Sontek hydrology instruments are renowned for their robustness, ease of use and practicality.

  flowtracker® 2 (ft2) handheld Acoustic Doppler Velocimeter (Adv)
The new FlowTracker2 (FT2) handheld Acoustic Doppler Velocimeter (ADV) had all the technology you have grown to know and trust with the original FlowTracker. Now comes with functional, modernized features (Bluetooth, GPS and a large colour screen, to name a few).FT2 handheld software is intuitive, easy to navigate and includes real-time plots of point data, QC parameters, and measurement verticals. Get defensible data correctly, the first time! With rugged construction for any climate and multiple display options for both day and night.

Sontek FlowTracker Portable Acoustic Doppler Velocitimeter

Designed with the field user in mind, the FlowTracker Handheld-ADV® (Acoustic Doppler Velocimeter) measures 2D or 3D currents, attaches easily to wading rods and features an automatic discharge computation using a varienty of international methods, including ISO and USGS standards.


Ideal for monitoring flows in small channels from 1 feet (0.3 m) to 16 feet (5 m) deep, the Argonaut-SW (Shallow Water) offers advanced Doppler performance for sites previously thought impossible to measure. Typically mounted on the bottom of a channel, stream, or pipe, the SW measures water level and vertically integrated velocity making it ideal for sites with reversing or stratified flow conditions.

Argonaut SL Acoustic Doppler Profiler Side-Looking

Inspired by the need for a simple way to measure water velocity and level in open channels, the Argonaut-SL. (Side-Looker) has earned worldwide acceptance as a long-term monitoring solution. Fully featured with accessories, mounting options, software, and a variety of integration formats, the Argonaut-SL fits your application in the way you need it to. Designed specifically for side mounting on bridges, canal walls, or riverbanks, the SL’s sleek low-profile housing makes installation easy.

Sontek S5/M9 Riversurveyor Acoustic Doppler Current Profiler

The RiverSurveyor S5/M9 systems give a new perspective to the notion of measuring open channel hydraulics. Using Sontek’s exclusive SmartPulseHD™, multiple acoustic frequencies are fused with precise bandwidth control for the most robust and continuous shallow-to-deep discharge measurements ever. A deterministic microcontroller expertly apportions the proper acoustics, pulse scheme, and cell size to get the highest definition possible so you can focus on the measurement, not the instrument setup. The system even has a vertical beam for precise channel definition and it’s all designed to work intuitively.
